It seems like Korach is very concerned about Middas HaGa’ava, and he cannot tolerate (his imagined) Ga’ava of Moshe and Ahron. Ga’ava was precisely Korach’s own problem, like Moshe told him: יִוֵל יֵנְבּ םֶכָל בַר טז ז You seek for too much, sons of Levi, and: הָנֻּהְכּ םַגּ םֶתְּשַׁקִּבוּ טז י Will you now also demand the Kehuna? etc. This is a common fallacy in human nature. If you are critical and you notice the Chesronos of others, you should suspect that the Chisaron you see is exactly your own problem that YOU should be always working on, instead of being busy "solving the world's problems".
In Novardok they taught me that it’s your lifetime job to sit on yourself ִל") ֶגי וֹא ןע ִז ףי ˂י (" הָלְיַלָו םָמוֹי day and night and try to improve yourself! This is why Dovid HaMelech was so great (like he said: יִתאָטַּחְו דיִמָת יִדְּגֶנ תהלים נא ה my sin is before me always) and this brings a Bracha to the entire universe, since: דיִחָי וֹלוּכּ םָלוֹעָה לָכְל ןיִלֲחוֹמ הָבוּשְׁתּ הָשָׂﬠֶשׁ יומא פו ב Even if just ONE person does Teshuva, the entire world is forgiven. וּאְשַּׂנְתִתּ ַﬠוּדַּמוּ “Why do you elevate yourselves” is exactly Korach’s own problem. He was an overqualified person, with greatness in Torah and Ruach HaKodesh and very rich.
Be Happy You Have Less, Even in Ruchaniyus; You Won't Become a Korach So Easily
He had: דָחֶא םוֹקָמְבּ הָלֻּדְגוּ הָרוֹתּ greatness in Torah and wealth combined in one person. It's not K'dai to be one of those who "has it all". The chances of becoming a major Baal Ga'ava are very strong. Be happy you have less, even in Ruchaniyus; you won't become a Korach so easily. And a Baal Ga'ava is critical of others, since he considers himself perfect. The more critical he is (albeit “L'shem Shamayim”) the more he himself is lacking.
These Days People Have an Inclination That Loves to Put Themselves Down
When Korach challenged Moshe’s leadership, Moshe davened to Hashem saying: I took nothing from the people, even a donkey. Despite his greatness in Torah (and he even had Ruach HaKodesh) Korach’s whole disaster was that he had a Negi'a (bias); i.e., he was jealous of: לֵאיִזֻּﬠ ןֶבּ ןָפָציִלֱא Eli’tzafan ben Uziel who was appointed Nasi of Kehas, and not him. So everything he was doing was Passul (disqualified) since a person with Negi’os isn't involved in the truth; he is only involved in his self-gain.
Moshe spelled out his purity in motives, since he had no Negi'a (gain). The Alter of Slabodka Zatzal had unusual success with his Talmidim. We can suggest that it was because he went all-out to be pure from Negi’os. If a Talmid was ever chutzpadik to him, he steered clear of giving that Talmid the harsh Mussar that he gave all his favorite Talmidim.
Because the Yetzer Hara to be depressed and to put yourself down is so strong these days, that people actually have a super strong Negi'a (motivation) to want to prove themselves wrong and to destroy themselves. A שׂוֹ ֵנא (enemy) is: ָפּסוּ ל ְל ֵﬠדוּת (disqualified to serve as a witness) and unfortunately there are loads of people who don't really love themselves, and are Passul (disqualified) whenever they judge themselves! Very, very often, you have to go extreme to ALWAYS be Dan yourself L'kaf Zechus.
Believe it or not, you may even have to be super extreme in insisting that you're okay despite your having done lots of evil. People feel guilty everywhere, for some reason or other. Here comes a major Chiddush: When you are Dan yourself L'kaf Zechus, you are actually acting with a purity since you are going against your nature that loves putting yourself down and negativity!
A Baal Ga'ava is actually not an Adam which means: ַא ָד ָמה the ground, and he deserves to be under the ground as if he never existed. When you are overqualified like Avraham Avinu whose name means: ָר ם "high", then you need to be humbly thankful for your great Torah and riches and to call yourself: רָפָﬠרֶפֵאָו זכ חי אריו dust and ashes like Avraham Avinu did. Or else it's a Korach who gets swallowed by the ground.
From: ָﬠ ָפר earth grows the most beautiful things, and from Ahron’s staff emerged blossoms and almonds. This is what a true Anav deserves. In Novardok they never stopped talking about how Hachna'a and Middas HaAnava can produce all kinds of goodness.
Hachna'a Causes You to Find Favor in Hashem’s Eyes, Which Brings Yeshuos
Many people have lots of problems with Bitachon, and they complain: “Why doesn't Hashem give me my wishes, after so much Bitachon and Tefila?” The answer is that basic Hachna'a is missing. They don’t realize that Hashem owes them nothing, and nobody likes a Baal Ga'ava’nik; so their demands boomerang and they lose their Chen (appeal) in Hashem 's eyes.
In Novardok I knew many situations where people got what they wanted, including Refuos, when they worked on humility! Going against your Ratzon can cause great Yeshuos in your life, since you are Mach'nia (humble) yourself. Just like you change your Tevah (nature), so does Hashem change the world for you. םיִוָנֲﬠַו ץֶרָא וּשְׁריִי אי זל םילהת The humble will inherit the earth (and delight in abundant peace).
